Answer:
Robert Hazen’s studied enviromental and biological processes that might have been critical for life, and also for the formation of approximately two-thirds of Earth's mineral species (see Hazen et al., 2008; Gonzalez & Richards 2020)
.
Explanation:
Hazen provided evidence about how first organic molecules were generated on the primitive earth millions of years ago. He observed that high-pressure hydrothermal vents may provide food for underwater ecosystems. It represents a piece of critical evidence on the origin of life.
You can read these articles that are certainly clarifying in the description of his experiments and discoveries:

Based on the given conversation above between Ben and his parents, the testable question for the hurricane research of Ben is option C: "Is the number of hurricanes increasing each year?" This is the testable question since they are arguing about the number of hurricanes in the past summers. Hope this helps.
Explanation:
Plants produce two gaseous waste products i.e. oxygen during photosynthesis and carbon dioxide during respiration. Excretion of gaseous waste in plants takes place through stomatal pores on leaves. ... Excess of water is also excreted from the plant body through the stomatal pores and from the surfaces of fruits and stems.
